ECOSYSTEM AND ENERGY FLOW

COMPONENTS OF AN ECOSYSTEM

• Biotic,are living factors. Plants, animals, fungi, protist and bacteria are all biotic
• Abiotic: non living organisms that affect all other organisms
• Pond, lake, ocean, mountain, desert are all examples of abiotic organisms

STRUTURE AND FUNCTION IN POPULATIONS

• The smallest unit of organization is single organism
• Which belongs to a population of other members of its species
• The population belongs to community of different species
• The community belongs to a community of different species
• The community and abiotic factors together from an ecosystem

LIMITING FACTORS

• Some limiting factors for population are food species and weather

ENERGY IN ECOSYSTEM

• Sunlight is the ultimate source of energy for most ecosystems
• energy flows from producers to consumers to decomposers in an ecosystem

PHOTOSYNTHESIS AND RESPIRATOON

• During photosynthesis cells capture energy from sunlight
• And transforms it into carbon dioxide gas and water into oxygen and sugars
• 6CO2+6H2O----(light energy) ----> C6H12O6+6O2

RESPIRATION

• During respiration cells break down simple food molecules and energy they contain
• C6H12O6+6O2----------> 6CO2+6CO2+6H2O+energy
• Cellular respiration occurs in the mitochondria of an organisms cell
• Photosynthesis and respiration can be thought of as opposite process

FOOD WEB

• Diffrent species that are connected together by what they eat

CARBON AND DIOXIDE AND OXYGEN CYCLE

• The water cycle is we're moving bodies of water
• The bodies of water move to different environments
• Water is essential for living things to grow and reproduce

CARBON AND OXYGEN CYCLE

NITROGEN CYCLE

• The nitrogen cycle is we're nitrogen moves from the air to the soil into living things and back in air
